Shellac-coated slices showed minimal water loss, which could be attributed to the lower water
vapour permeability rate of shellac (Table 2).
Hagenmaier and Shaw (1991) also reported high barrier properties of shellac coatings towards respiratory gases and water vapours. Aloe gel was also found to retard the moisture loss Composite coatings of polysaccharide lipid are known to increase water barrier efficacy with increased lipid content and in turn cause more weight loss (Perez-Gago, Rojas, & del Rio, 2002). Aloe gel, which mainly consists of polysaccharides, was highly effective as a moisture barrier with and without lipid incorporation
